Deep Time Maps™ Paleogeography (the new trade name for paleogeographic maps produced by Colorado Plateau Geosystems, Inc.) provides paleogeographic maps of the ancient world. The maps show the varied landscapes of the ancient Earth through hundreds of millions of years of geologic time including distribution of ancient shallow seas, deep ocean basins, mountain ranges, coastal plains, and continental interiors. Tectonic features shown include subduction zones, island arcs, mid-ocean ridges and accreting terranes. Latest geologic data from the scientific literature are used to compile and construct the ancient Earth. Maps are available for all major divisions of geologic time: Precambrian, Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian -- Carboniferous -- Permian, Triassic, Jurassic, Cretaceous, Paleogene, Neogene, -- Tertiary -- Pleistocene, Quaternary Paleogeography.

Paleogeographic maps have multiple uses. Paleogeography is a synthesis and can only be accomplished from extensive geologic data. Therefore, paleogeographic maps portray immense amounts of data in a single view. This may be their single greatest value. They also show this data in a way that is interpretable to non-geologists. When used in time sequence, they show trend and pattern through geologic time. They readily display distribution of ancient geologic features at the surface of the Earth. They teach both geologists and non-geologists broad patterns of Earth history. They help satisfy our curiosity concerning what the Earth used to look like – they educate and stimulate.
